noLrH, a c; ze! ,if the United States, residing at Coscoh, in the county of Fairfield and State of Connecticut, have invented new and useful Improvements in Motor-Car-Loclnng Devices, o? vliifh the following is a specifi-` cation.

My invention relates to motor car locking devices, und. its objects are to lock the steen ing wheels of a motor car, to break the connection of the electric system lor sparking und to lock the sume against remaking,

operate each of the locking mechanisms s1- multaneously from the same lever, and to produce a simplified and effective construction.

My invention primarily consists in mounting a clutch upon the steering post of an automobile and operating the same through a lever which may he locked when the clutch closed, thereby locking the steering mechanism.

My invention further consists in mounting;` upon the operating lever a knife blade contact arranged to engage with a coperatv lug contact and to open the sparking circuit when the clutch is'closed and the steering mot-l 1 a ni sin locked.

M v invention further consists in the verious improvements and novel. constructions illustrated in. the drawing and more specifically hereinafter lpointed out and claimed.

Attention is hereby directed to the aecompanying drawing in which similar numerals of designation refer to similar parts throughout the several views.

Figure 1 is a sideelevation of my im- 'iuoved device showing the same "in its noriual position adjacent to the dashboard, and

- with clutch Aclosed;

` Fig. 2 a diagonal sertionmf the locking chamber shown in Fig. 1 taken in a tion parallel to the steering,r post;

Fig. 3 is an enlarged view of a port in ol? 'Fig'. l, showing,r a section of the locking chamber on line 3-3 of Fig. 2., lookinir in the direction of the arrows, and showing the clutch open;

Fig. 4. is an enlarged View simil-.ir imchan acter to Fig. 3, showing a sertionof the lorlrinpr chamber on line fl-fl ol': 2;,looking in the direction of the arrows, end show-- ing the clutch Closed;

direcpurpose.

Fig. 5 is a plan View of the clutch and locking chamber and adjacent parts, the

wall of such chamber being .shown in section Fig. 7 is a View in perspective of the lock iup,` lever.

ln the drawing, the sleeve 8, mounted upon the steering post 9 of an automobile is secured to the dash-hoard 1() by means of the liunge l1, screws .l2 serving for such The lower end `of said sleeve 8 is provided with the teeth 13, which are arranged to mesh with the teeth 14 of the sleeve of the clutch 15, which is likewise mounted upon the steering post,9 and engages with the spline 1G therein, and is thereby held against rotation.

Upon the lower end of the clutch 15 is mounted the collar 1T, to which is secured one end of the lever 18 by means of the bolt 19. The upper end of the lever 1,8 passes through an opening in the dash-board 10 into the locking chamber 20. and is provided with the operating handle 21 extending outside said chamber Vthrough the slot 32. The lever 18 has adjacent to said handle 21, the roove 30, which is arranged to engage with the holt 31 of the combination look 24 mounted upon the hinged cover 25 of the chamber 20.

For the purpose of breaking the sparking circuitl provide the lever 18 with the knife contact 22 which is insulated therefrom and is arranged to engage with the cooperating divided contact 23,A which is secured to the dash-hoard 104 and thc shank 26 of which extends therethrough and is insulated therefrom.. The wire 2T secured as shown to the to the binding4 post 29 serve as 'a means o incorporating'these contacts in the electric circuit operatiner through thesperk plugs.

, To lock my d v iee by ngeis 'of the handle 21, vI raise the lever 18, which is normally in the position showniin Fig. 3, to the position shown in Figs. "1, 4 and 5, at which time the clutch 15 will be in engagement with the sleeve El, and the lever may be locked in position by means of the bolt 31 ol the lock 24. At the same instant as will he observed, the knife blade 22 will have broken the connection with the Contact 23,

null the spul-king (tii'lnit will liv lirolien. Thus, until the i'oruhinut-ion loek4 :5l is nnloi'luzl. lioth llnA electric fili'nit unil the steering,a feur will he out of vonnnission.

l Hlnh time (he Sleeve H is swnreil nnuinHl, rolntion lioth by reason ol' the ilu-lined llnnge resting nguinst the. ihlnlilioniwl nnfl hy reason ol thv Hiiews sevuring the I@une thereto The teeth 14 ol' the i-lutifh 'l5 lining;l in i-lone engngjenu-ut with the teeth ,lil ol' th(I sleeve H. the rlntifh 15 is :ilso held against rotation. und hei-:inse of its engagement with the spline l( prevents the turningl of the Steering post i). No amount of force cnpalile ol' heine exerted nnniunlly upon the wheel 2112i will in suoli use :sulliffe to turn it.

At any time ilesireil the operntiwness of the steering nim-lmnsin inni' he quirkly re stored in the person rightfully in poeseifsion ol' ilu` vnr upon hie: lullin-hin; the holt lll. unil pushingr the lnlnille 2l lim'h' into norv unil position.
